Are there any green light cob's, for plant maintenance and such.

Not that im aware of, but you can buy green monos

How could I daisy chain a couple of clu0481818 builds is it possible ?

 

[nevergoodenuf]

@mypassion you can buy green led light bulbs at Home Depot. The are very bright for a 9 watt bulb.

I wanna use a led that I have and make it full cxb3590. I was thinking to run 2 times 4 cxb on MW1400 and find a green one to place it in the middle (9 clusters) but I will do 4+driver and 5+driver. I will try to build a in line hood for it, but it's a future future x5 project. We don't have home depot. Most consumables I can find, but the top tech stuff not so much.

Like, the AC?

Basically instead of 2 plugs you would plug 1 light into the other

@mypassion when I have to work in my room at 'lights out', I always try to avoid shining the light directly at the plants. I wouldn't want that intense of a green light directly on my plants when the lights are out, maybe 4 diodes on stars in each corner, but that will be pretty bright also.

I am just putting this out there... Under the section, "Thermal Interface Material." Do you have stock of Arctic thermal pads for the CLU 048 diode?

Personally speaking, I realize we can use the Arctic thermal pads for the CLU 058 diode with the CLU 048 diode if we cut some of the excess off.

 

[CobKits]

i cut them myself from sheets, the 048s are the same size as the cxb3070 +/- 1mm

ill put a separate listing up there for 048- for now you can order 058 and leave me a note

Hey. I'm wanting to run 8 cxb3590s at 36v and 1400mA in a 4x4. Should I use pin heat sinks, or the 5.886" profile from HS USA?

 

[CobKits]

@ 50W per cob any of the heatsinks on our site would be fine.

as far as the 5.886 HSUSA, youd need 3" of heatsink per cob if actively cooled ($5 per), or 10" per cob passive ($17 per)

the pinfins would outperform the hsusa in passive, but youd need a frame for them, whereas the hsusa is a frame (but you have to tap it! -nothing's free huh!)

Thanks sir. If I will ever need it I will buy a bulb or better night vision

Cree is making 200w cob's. All prices dropping for cxb3590 and below.

 

[CobKits]

yes we will see. im guessing these new crees will perform somewhere between the $42 citi 1825s and the $60 3618s, so its really all about the price... they need to be $45 or less to be competitive with current offerings

You gonna offer any 3618's?

Cree will likely be way more expensive!!

100V cobs seem like an outlier. Youre the first person to ask about them

1825s are a better value in lumens/dollar at a given efficiency

at 160 lm/W
3 1825s = 22570 x 3 = 67710 lm
2 3618s = 24660 x 2 = 49320 lm

It's cause your account is too new. You'll be able to soon enough just stay active.

 

[Uberknot]

Not to be a pessimist, but your CREE CXB3590s you are selling for $44.00 are selling for ~$33 elsewhere. Is there something else you are providing with the chips that I'm not seeing?

where?
